Why POST requests are turned into GET in django with wsgi? - django

Question

I have a Django 1.9.4 site.
In localhost, I could easily submit the form and have the results that I want.
But when it's on the server, the POST request turns into a GET request.
On local, I use python manage.py runserver but on server I use Apache2, WSGI
Local:
django 1.9.4
python 2.7.10
Ubuntu 15.10
Server:
same django
python 2.7.6
Server version: Apache/2.4.7 (Ubuntu)
Ubuntu 14.04
Server example.com.conf:
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
ServerAdmin email#gmail.com
Alias /static /var/www/example.com/static
<Directory /var/www/example.com/static>
Require all granted
</Directory>
Alias /media /var/www/example.com/media
<Directory /var/www/example.com/media>
Require all granted
</Directory>
<Directory /var/www/example.com/wh>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIDaemonProcess webhistory python-path=/var/www/example.com:/var/www/example.com/env/lib/python2.7/site-packages
WSGIProcessGroup webhistory
WSGIScriptAlias / /var/www/example.com/wh/wsgi.py
ErrorLog /var/www/example.com/logs/error.log
CustomLog /var/www/example.com/logs/access.log combined
Alias /robots.txt /var/www/example.com/robots.txt
Alias /favicon.ico /var/www/example.com/favicon.ico
</VirtualHost>
And the wsgi.py:
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "wh.settings")
application = get_wsgi_application()
And the craziest part is that even my admin app doesn't work properly.
All the POST submitted forms turn into GET ones.
Here is the error:
request <WSGIRequest: GET '/someurl/'>
What's the problem?
Is it related to APPEND_SLASH = True?
And here's what's realley bothering me... The form submission worked once! why isn't it working again?
